Abstract
The invention discloses a radiating structure of an LED lamp. The radiating structure of the LED lamp comprises an aluminum substrate and the LED lamp. The aluminum substrate is composed of a resistance welding layer, a copper cladding layer, an insulating layer and an aluminum sheet from top to bottom sequentially. The aluminum sheet is connected with a radiating aluminum profile through silicone grease. An electrode of the LED lamp is connected with the resistance welding layer. Through grooves are arranged at positions, corresponding to a base of the LED lamp, of the copper cladding layer and the insulating layer. The base of the LED lamp is welded to the aluminum sheet. The radiating structure of the LED lamp is characterized in that structure is simple, radiating effect is good, stability of the LED lamp is increased, and service life of the LED lamp is prolonged.
Description
Technical field
The present invention relates to the Design of Luminaires field, be specifically related to a kind of LED lamp radiator structure.
Background technology
The core of LED is a PN junction, and injected electrons and PN junction compound tense directly convert electric energy into luminous energy, but the luminous energy of not all conversion all enough is transmitted into outside the LED; It can be absorbed sheet in PN junction and epoxy resin/silica gel inside and change into heat energy, and this heat energy produces huge side effect to light fixture, if can not efficiently radiates heat; The LED internal temperature is raise, and temperature is high more, and the luminous efficiency of LED is low more; And the life-span of LED is short more, under the serious situation, can cause the LED wafer to lose efficacy at once; So heat radiation is still the huge obstacle that great power LED is used; Find in the use that the insulating barrier heat flow density of heat-radiating aluminum plate is high more a lot of than the heat flow density of other layers, be the insulating barrier of heat-radiating aluminum plate so can obviously find out the heat radiation bottleneck.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of LED lamp radiator structure is provided.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: LED lamp radiator structure; Comprise aluminium base, LED; Said aluminium base from top to bottom is made up of solder mask, copper-clad, insulating barrier, aluminium sheet successively, and said aluminium sheet is connected with the heat radiation aluminium section bar through silicone grease, and the electrode of said LED is connected with solder mask; The position base of the corresponding LED of said copper-clad and insulating barrier is provided with groove, and the base of said LED is welded on the aluminium sheet.
The base of LED is through soldering tin metal layer on the aluminium sheet and aluminium sheet welding.
Characteristics of the present invention are: simple in structure, good heat dissipation effect has increased the stability of LED light fixture, the service life of having improved the LED light fixture.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: 1, aluminium base 101, heat radiation aluminium section bar 102, silicone grease 103, aluminium sheet 104, insulating barrier 105, copper-clad 106, solder mask 107, scolding tin metal 2, LED 201, electrode 202, base.
The specific embodiment
As shown in Figure 1, LED lamp radiator structure of the present invention comprises aluminium base 1, LED2; Said aluminium base 1 from top to bottom is made up of solder mask 106, copper-clad 105, insulating barrier 104, aluminium sheet 103 successively; Said aluminium sheet 103 is connected with heat radiation aluminium section bar 101 through silicone grease 102, and the electrode 201 of said LED2 is connected with solder mask 106, and base 202 positions of said copper-clad 105 and insulating barrier 104 corresponding LED2 are provided with groove; Make aluminium sheet expose out; Base 202 with LED2 welds through soldering tin metal layer on the aluminium sheet 103 107 and aluminium sheet 103 then, and during use, the heat that the PN junction of LED2 sends is dispersed in the air through base 202-aluminium sheet 103-silicone grease 102-heat radiation aluminium section bar; Remove the very little insulating barrier 104 of thermal conductivity factor, made heat-sinking capability strengthen greatly.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
